warpmovie3d: Creates a sequence of images showing predefined steps of warping two meshes or landmark configurations (2D and 3D) into each other

Description

Creates a sequence of images showing predefined steps of warping two meshes or landmark configurations (2D and 3D) into each other

Usage

warpmovie3d(x, y, n, col = "green", palindrome = FALSE, folder = NULL,
  movie = "warpmovie", ...)
# S3 method for matrix
warpmovie3d(x, y, n, col = "green", palindrome = FALSE,
  folder = NULL, movie = "warpmovie", add = FALSE, close = TRUE,
  countbegin = 0, ask = TRUE, radius = NULL, links = NULL, lwd = 1,
  ...)
warpmovie2d(x, y, n, col = "green", palindrome = FALSE, folder = NULL,
  movie = "warpmovie", links = NULL, lwd = 1, imagedim = "800x800",
  par = list(xaxt = "n", yaxt = "n", bty = "n"), ...)
# S3 method for mesh3d
warpmovie3d(x, y, n, col = "green", palindrome = FALSE,
  folder = NULL, movie = "warpmovie", add = FALSE, close = TRUE,
  countbegin = 0, ask = TRUE, radius = NULL, xland = NULL,
  yland = NULL, lmcol = "black", ...)

Arguments

x

mesh to start with (object of class mesh3d)

y

resulting mesh (object of class mesh3d), having the same amount of vertices and faces than the starting mesh

n

integer: amount of intermediate steps.

col

color of the mesh

palindrome

logical: if TRUE, the procedure will go forth and back.

folder

character: output folder for created images (optional)

movie

character: name of the output files

…

additional arguments passed to shade3d (3D) or points (2D).

add

logical: if TRUE, the movie will be added to the focussed rgl-windows.

close

logical: if TRUE, the rgl window will be closed when finished. width and 200 the height of the image.

countbegin

integer: number to start image sequence.

ask

logical: if TRUE, the viewpoint can be selected manually.

radius

numeric: define size of spheres (overides atuomatic size estimation).

links

vector or list of vectors containing wireframe information to connect landmarks (optional).

lwd

numeric: controls width of lines defined by "links".

imagedim

character of pattern "100x200" where 100 determines the width and 200 the height of the image.

par

list of graphial parameters: details can be found here: par.

xland

optional argument: add landmarks on mesh x

yland

optional argument: add landmarks on mesh y

lmcol

optional argument: color of landmarks xland and yland

Details

given two landmark configurations or two meshes with the same amount of vertices and faces (e.g a mesh and its warped counterpart), the starting configuration/mesh will be subsequently transformed into the final configuration/mesh by splitting the differences into a predefined set of steps.

A series of png files will be saved to disk. These can be joined to animated gifs by external programs such as imagemagick or used to create animations in PDFs in a latex environment (e.g. latex package: aninmate).

Examples

# NOT RUN {

###3D example
 data(nose)##load data
# }
# NOT RUN {
##warp a mesh onto another landmark configuration:
longnose.mesh <- tps3d(shortnose.mesh,shortnose.lm,longnose.lm,threads=1)

warpmovie3d(shortnose.mesh,longnose.mesh,n=15)## create 15 images.

### ad some landmarks
warpmovie3d(shortnose.mesh,longnose.mesh,n=15,xland=shortnose.lm,
            yland=longnose.lm)## create 15 images.


### restrict to landmarks
warpmovie3d(shortnose.lm,longnose.lm,n=15,movie="matrixmovie")## create 15 images.

### the images are now stored in your current working directory and can
### be concatenated to a gif using an external program such as
### imagemagick.
